Q

You are flying a jet at FL300. The tropopause is at 36,500 feet. Assuming similar winds and standard temperature lapse rate, a climb to FL360 would be advantages, in part, because:
1. A greater amount of air is available for combustion.
2. Less drag exists to slow down the compressors, thereby allowing the engines to run at a higher RPM.
3. At a low altitude, the engine RPM necessary to produce the required thrust is low and, generally, well below the normal rated value. An increase in engine speed to the normal rated value will reduce the
specific fuel consumption.
4. Less drag exists on the airframe. However, there is no advantage for the engines, as specific fuel consumption is essentially the same for jet engines at altitudes from approximately FL250 up to the tropopause.

A

At a low altitude, the engine RPM necessary to produce the required thrust is low and, generally, well below the normal rated value. An increase in engine speed to the normal rated value will reduce the specific fuel consumption.

61
Q

You are level at your cruise altitude of FL310 at a speed of Mach .83. ATC tells you to maintain a speed of no greater than Mach .80. You pull the thrust levers back and the engines decelerate. The engine are decelerated because:

  1. The turbine power exceeds the compressor power required to maintain Mach .83.
  2. The turbine power is less than the compressor power required to maintain Mach .83.
  3. The power extracted by the turbine will equal the power required to operate the compressor.

A

The turbine power is less than the compressor power required to maintain Mach .83.

74
Q

When wing fuel tanks on certain heavy aircraft, such as the MD-11, get below a certain fuel quantity, VMO/MMO is reduced. The primary reason for this is because:

  1. The weight of the fuel in the wing fuel tanks that has been burned off is no longer available to provide added structural stability required at higher true airspeeds.
  2. The weight of the fuel in the wing fuel tanks that has been burned off is no longer available to provide added structural stability required at higher indicated airspeeds.
  3. Without the added weight of the fuel on the wing, the angle of attack increases, making the aircraft more susceptible to Mach tuck at higher airspeeds.
  4. Without the added weight of the fuel on the wing, the angle of attack increases, making the aircraft more susceptible to wing twist at higher airspeeds
